Hello ALL,
i am working on imx6q sabre AI board, i want to interface the 3.5" LCD with touch(LCD Driver IC is ST7789S) and (touch driver ic FT6306DMB), LCD Display is bring up successfully, but i am struggling in bring up TOUCH on this LCD, i am using the 3.10.53 kernel version on target board, for this i copy the driver file from boundatydevices.i.e ft5x06_ts.c (linux-imx6/ft5x06_ts.c at boundary-imx_3.10.53_1.1.1_ga · boundarydevices/linux-imx6 · GitHub ) and modify the my kernel source code as below like this,
In imx6q-sabreauto.dts file
&i2c2 {
status = "okay";
};
========================================
In imx6qdl-sabreauto.dtsi
&i2c2 {
clock-frequency = <100000>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c2_3>;
status = "okay";
/*
egalax_ts@04 {
compatible = "eeti,egalax_ts";
reg = <0x04>;
interrupt-parent = <&gpio2>;
interrupts = <28 2>;
wakeup-gpios = <&gpio2 28 0>;
};
*/
polytouch: edt-ft5x06@38 {
compatible = "ft5x06,ft5x06-touch";
reg = <0x38>;
pinctrl-0 = <&edt_ft5x06_pins>;
interrupt-parent = <&gpio3>; //find int
interrupts = <18 2>;
wakeup-gpios = <&gpio3 19 0>; //find reset
//linux,wakeup;
};
